Sttp 2 Install the boiler in a 'oat bon that allows proper routing of all \l!nc and air
piping to the selected sidewall location.
Sttp 3
Make sure the selecced sidewall termination 'ocation complies with Fig-
ure
4 1,
page
35.
(Muhiple boiler sidewall places must also comply with
Figure 48, page 40.)
Sttp 4 Use only
the
veru materials Listed in Figure 40. page
33.
Provide pipe adapt-
ers where required. Vent piping and air piping lengths must not exceed
the
values
shown in Fig.ure
39,
page
32.
St tp S Prepare
the sidewall penetrations and
secure
the sidewall plates
as instructed
in this section. See •prepare wall peneu ations• on page
40.
Sttp 6 The
air piping mu.<;t: termi:nate in a
down-tumcld elbow as shown above.
The vent piping
must terminate in an tlbow pointed outward or
INlay
1rom
the
air Jnlet
as shown above. See illustration above.
Sttp 7
Install \'eat and ai:r piping
between
the boiler and the sidewall openin&$-
Siope horizontal piping downward coward the boiler at least 114 inch
per
foot. See page 48 for general guideli:nes.
Sttp 8
Install pipe supports e'l'e:f'Y

feec on both the horizon cal
and vertical runs.
Install a hanser support within 6 inches of any upturn in
the
piping.
Sttp 9 Attach
the
wmt tmnination exterior piping: U se
either
of thec.onfigunttions
shown above, as needed to ensure clearance abo\>e grade or snow Line:.
Sttp 10
The vent and air pipes
may run up as high as 4 feet
with no enclosure.
The
\'C!OC
and air
pipes
must
be secured with braces, and all dearances and
lengths
must be nwuntained.
Space
braces no further ttum
24
inches aparc.
Sttp 11 External \'tilting greater than 4 feet requires an insulated enclosure around
the \'tnt and air pipes. The vent and
air cenninations must
exlc through
the mdo:sute as shown in the illustration above, maincai:ning all required
clearances.
